Quick start
- Open the Future Value Calculator.
- Enter principal for the money already saved or invested.
- Use the first example, "Monthly saving: $5,000 start plus $250 monthly for 10 years at 6%", if you want to see a filled-out estimate before entering your own values.
- Calculate, read the formula line, then copy the result only after the amounts, percentages, time periods, or assumptions look right.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Project a savings or investment balance.
- Compare payment frequencies and return assumptions.
- Separate growth from total contributions.
- Use alongside present value for time-value math.
What this calculator is for
The Future Value Calculator moves money forward in time. It estimates what a starting balance and equal regular payments could become if the entered rate, time, and payment frequency stay the same.
Good fit examples: Project a savings or investment balance. Compare payment frequencies and return assumptions.
What to enter
Finance estimates are sensitive to small input changes. Check whether a field expects a monthly amount, annual amount, dollar value, or percent before calculating.
- Enter principal for the money already saved or invested.
- Enter payment for the amount added each period, then set payments per year to match that payment amount.
- Enter annual rate and years as planning assumptions, not as guaranteed growth.
Example walkthrough
Try the calculator example: Monthly saving: $5,000 start plus $250 monthly for 10 years at 6%. The example result is About $50,066.82 future value, with $35,000.00 contributed.
- $5,000 plus $250 monthly for 10 years at 6% compounds the $5,000 and each monthly payment separately.
- The calculator treats regular payments as end-of-period payments, so the timing is closer to an ordinary annuity than money deposited at the start of each period.
Formula and steps
In plain language: The calculator compounds the starting amount and compounds each regular payment using the selected payment frequency, then adds both future value parts. For the default example, $5,000 plus $250 monthly for 10 years at 6% projects about $50,066.82, with $35,000.00 contributed and about $15,066.82 modeled growth.
If the estimate looks surprising, check the formula and inputs before using the answer in a budget, comparison, or planning note.
How to read the answer
Start with the headline result. Then read the supporting lines to see what made the number larger or smaller, such as rates, time periods, costs, taxes, fees, discounts, or contributions.
- Future value is the projected ending balance.
- Principal future value shows what the starting amount becomes by itself.
- Contribution future value shows the growth of the regular payment stream.
Common mistakes to avoid
Most bad finance estimates come from mixing rates, terms, monthly amounts, and annual amounts. The other common mistake is using a planning estimate as if it were a final quote.
- Do not mix monthly payments with annual payment frequency.
- Do not treat the entered rate as guaranteed investment performance.
- Do not forget that taxes, fees, inflation, missed payments, and account rules can change the real result.

FAQ in plain language
When should I use the Future Value Calculator?
Use it when you want to test the exact inputs on this page: Project a savings or investment balance. Compare payment frequencies and return assumptions. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Future Value Calculator inputs mean?
Starting amount means the balance you already have before new payments and modeled growth. Regular payment means the amount added each period. Match this to the selected payment frequency. Interest / return rate means the annual rate entered as a normal percent, such as 6 for 6%. Years means how long the projection runs. The calculator rounds the number of payment periods from years times payments per year. Payments per year means how often the regular payment is made, such as 12 for monthly or 1 for yearly.
What is future value?
Future value is the projected ending balance after a starting amount and any regular payments grow over time at the rate you enter. It is a planning estimate, not a promise of actual investment performance.
How does this calculator handle regular payments?
It treats regular payments as end-of-period payments, similar to an ordinary annuity. A payment made at the beginning of each period would usually grow slightly more because it has one extra period to compound.
Should I enter an annual rate or a monthly rate?
Enter the annual rate as a percent. The calculator divides that rate by the payment frequency, so monthly payments use one-twelfth of the annual rate in each monthly period.
Does future value include inflation, taxes, or fees?
No. The result is a before-tax, before-fee projection in today-dollar terms. Inflation, taxes, account fees, contribution limits, and market losses can all change the real buying power or final account value.
What is the difference between future value and present value?
Future value moves money forward to estimate a later balance. Present value moves future money backward to estimate what it is worth today at a chosen discount rate.
